Methods for providing electrically-conductive articles

摘要

A method is used to provide an electrically-conductive article. This method includes: forming an electrically-conductive pattern on first supporting side of a transparent substrate that also comprises an opposing second supporting side; and forming a dry outermost polymeric coating over at least part but not all of the electrically-conductive pattern, the dry polymeric coating having a dry thickness of less than 5 μm, an integrated transmittance of at least 80%, and comprising a non-crosslinked thermoplastic polymer having a glass transition temperature (Tg) that is equal to or greater than 65° C.

1. A method for providing an electrically-conductive article, the method comprising:
forming an electrically-conductive metal pattern on first supporting side of a transparent substrate that also comprises an opposing second supporting side, which electrically-conductive metal pattern comprises at least:
an electrically-conductive metal grid, andan electrically-conductive metal connector that is connected to the electrically-conductive metal grid; and forming a dry outermost polymeric coating over 100% of the electrically-conductive metal grid, but over less than 100% of the electrically-conductive metal connector, the dry polymeric coating having a dry thickness of less than 5 μm, an integrated transmittance of at least 90%, and comprising a non-crosslinked non-aromatic thermoplastic polymer having a glass transition temperature (Tg) that is equal to or greater than 65° C.,
wherein the non-crosslinked non-aromatic thermoplastic polymer is one or more of the following:poly(methyl methacrylate-co-n-butyl methacrylate);poly(methyl methacrylate-co-n-butyl methacrylate-co-methacrylic acid);poly(methyl methacrylate-co-hexyl methacrylate);poly(methyl methacrylate-co-octyl methacrylate);poly(methyl methacrylate-co-lauryl methacrylate);poly(ethyl methacrylate-co-n-butyl methacrylate-co-methacrylic acid); andpoly(ethyl methacrylate-co-methacrylic acid),wherein the mol % of the recurring units derived from methyl methacrylate or ethyl methacrylate in the non-crosslinked non-aromatic thermoplastic polymer is from 75 mol % to 95 mol %, based on the total recurring units in the non-crosslinked thermoplastic non-aromatic polymer.
